I just bought a second hand m16 2022 a little over a month ago and it had an initial problem. The charger that came with it got oxidation on the inside of the barrel while it was in transit. Whenever I played heavy games on it or put load on it, the charger would shut off and the LED indicator on the chassis wouldnt light up. It charges fine when used lightly, and PD type c doesnt have the same issue. I decided to buy a replacement powerbrick and it solved the issue, i could play games now without worrying about battery drain.
Now, it started having this weird issue where the screen would turn off and when i pressed any key to turn it on it would lead me back to the lockscreen and i had to sign in again, and it would turn off and sign me out again shortly after.
After one or two signouts, it would shutdown with no error screen, sometimes try to restart on its own, and sometimes I have to press the power button. At first it was just restarting on its own, but now it leads me to the language setup screen and when I run diagnostics from that page it would say that it cant repair my pc so i either go to advanced options or shut down. Then it got worse after a day or two when it would randomly die and all the LEDs would go out, including the middle charging LED despite it being plugged in. Wouldnt start, no fans, black screen. Then after a little bit it would let me turn it on and when I press the power button, the keyboard lights up and the screen backlight turns on, ROG symbol appears, then everything turns off again including LED lights. This happens for a bit where i turn the keyboard on, rog logo appears, then everything goes out and id have to wait for a few minutes before trying again.
When I finally manage to log on, i open ghelper to see it on standard mode, and when I set it back to igpu mode it would die shortly after and return to standard mode. I ticked all the boxes like avoid using gpu on apps and other settings in ghelper. I tried letting it run on standard to see if its just the igpu but still the same issues. Thermals arent hot and no sign of throttling. It doesnt interrupt me most of the time when im playing games but when I'm not the chances of that issue popping up is higher. See the video attached.
Update: Opened up the chassis and found a tiny capacitor near the charging port and fan was dislodged and moving around freely in the chassis I'm glad I spotted it. My guess is it was bridging some other traces, shorting out the board especially since it was near where the display cable attaches to, causing the screen blackouts but doesn't explain the shutdowns and sign outs. Issue has stopped upon removal of the capacitor. Hopefully this fixes it and i hope it helps anyone else who might be facing a similar problem.
Update 2: The issue has now been resolved. I took it to a technician along with the capacitor in a ziploc bag and he did a board checkup. He said no further repairs are required and he says that due to the nature of how I found the capacitor and that it was detached instead of just being loose and hanging, he cannot pinpoint its original location and would probably be more risky to attach it somewhere its not supposed to be as he has no prior experience working with Zephyrus motherboards.
